FRAME FOR HOLDING COPYING-PLATES.

SPECIFICATION forming part of Letters Patent No. 404,034, dated May 28, 1889.

Application filed October l1, 1887. Serial No. 252,004. (No model.)

To aZZ whom, may concern:

Be it known that I, ALBERT B. DICK, residing at Chicago, in the county of Cook and State of Illinois, and a citizen of the United States, have invented a new and useful Improvement in Frames for Holding Copying- Plates, of which the following is a specification, reference being had to the accompanying drawings, in whichy Figure l is a top or plan view showing the frame on the base. Fig. 2 is a bottom View of the frame; and Fig. 3 is a cross-section, enlarged, of the frame and base.

Plates for reproducing a number of copies of circulars, letters, zc., are made from paper perforated to have thereon the matter to be reproduced, and such plates have been used in connection with a movable frame and fixed base.

The object of my invention is to improve the construction of such devices, which I accomplish as illustrated in the drawings, and hereinafter described.

That which I claim as new will be pointed out in the claim.

In the drawings, A represents a rectangular frame, of iron, brass, or other suitablematerial, and of dimensions for the size of the copying-plate used.

B is a frame, of wood or other suitable maferial, having therein a groove, d, to receive the frame A.

C is a fastener having an engaging end, l), to pass over the frame Awhen in the groove a of the frame B, and having a handle, c, by which the end b can be turned to engage with or be disengaged from the frame A, and, as shown, three of these fasteners C are used on each side of the frame and one at one end thereof.

D are plates secured to the sides and end of the frame B, as many plates being used as there are fasteners C, and each plate having an ear, in which is a pin or pivot, d, on which is mounted a fastener, C.

E E are two long ears secured on opposite sides of the frame B at the rear corners and extending rearwardly and downwardly therefrom. Each earE has a hole for the passage of a pin or pivot, the pin c for one ear projecting out from the corner of the base, and the pin e for the other ear being movable to permit the frame B to be pivotally attached to the base at one end, so that it can be raised and lowered or removed.

F is a spring-plate carrying the pin e and .secured at one end to the base.

G is a base made of wood or other material, and in dimensions somewhat larger than the frame B.

H is a sheet of paper on which the copy is to be reproduced, which paper lies iiat on the base G to receive the copy.

I is the paper plate, having thereon the matter which is to be reproduced on the paper Il. This plate is made of a sheet of paper perforated with the letters and characters for the matter to be transferred, and in size is somewhat larger than the frame A in one or both directions, so that it can be laid on the under side of the frame B, and the frame A placed thereon and forced down into the groove a, carrying with it the edges of the plate I, as shown in Fig. 3, by which the body of the plate will be drawn taut, so that the ink-roller can be run thereover without liability of displacing or moving the copying-plate. The copying-plate I, if of sufficient length and width, is forced into the groove a by the frame A at both its ends and sides; but if of a less length than the frame A one end only and the two sides can be forced into the groove a.

.I are Wire clips located two on each side of the base G, and under which a blotting-pad can be placed and securely held when desired, on which pad the sheet of paper, H, to receive the copy can be placed.

In use the copying-plate I already prepared is secured in position on the frame B by forcing its edges into the groove a by the frame A, and after the frame A has been forced down the fasteners C are turned to have their ends l) engage the frame A, which holds the frame securely in place and secures the plate I on the under side of the frame B in a firm manner and perfectly straight and taut. The frame B is then attached to the base G by Slipping the ear E of the pin c over such pin, and then inserting the movable pin e into its ear E, which pivotally connects the frame B, with the copying-plate I thereon, to the base G. A sheet of paper, H, is inserted on the base G beneath the matter of the copyingplate I by raising the frame B from the base ICO G, and when the sheet of paper, H, is in position theframeB isdi'olpped, bringing'the copying-plate I in Contact with the paper, H, so that by running an inking-roller over the top surface of the copying-plate thematter thereon will be transferred to the paper, AH, after which the frame B can be raised and the sheet of paper, H, with the matter thereon removed and a fresh sheet inserted and the plate I again dropped, and so on until the desired number of copies has been made.

After the copying-plate I has been used to the extent required it can be removed by withdrawing the movable pin e from its ear E and removing the ear of the pin e therefrom, disengaging the frame B from the base. The fasteners C can then be turnedto disengage the ends thereof from the frame A, so that by striking the frame B the frameA can be forced from the groove a, allowing the ,removal of the used plate I and leaving the frames free for the insertion of a new plate in the manner described.

By hinging the framerB to the base G by means of the long ears E the `frame B, when its forward end is lifted, is raised from the base G at its rear end, so that the paper which has received the impression can be readily and quickly removed from the base G by passing through the space between the frame B and the base G at the rear end. The ears E, being at the sides of the frame B, do not interfere with the removal of the paper.

Vhat I claim as new, and desire to secure by Letters Patent, is-

The frame A, fraine B, having the groove a, copying-plate I, fasteners C, and ears E, in combination with the pins e e', spring-plate F, and base G, for securing the copying-plate in position for use, substantially as described.

Atenei* isL bien.
